They have stolen bitcoins from my official Bitcoin wallet.
Wallet had the password (about 30 characters)
Last time I've entered the password at least 6 months ago.
I installed Windows 10 in October.
Kaspersky Internet Security says no viruses.

official wallet?

After seeing his russian thread(translated) I believe he is talking about blockchain.info ,and that OP is heckin not the official wallet.
Well the discussion on the russian thread was pretty much about blockchain.info.

official wallet?

Bitcoin core 10.2

[ranochigo]

There is no official Bitcoin wallet, the reference client is Bitcoin Core if that is what you meant.

The coins were sent away in an hour after the payment was first received. You did not have any Bitcoins when you typed the password 6 months ago and hence it would be possible that a script was designed to transfer your coins away once a payment was detected. It could also have been compromised when your wallet was first installed. It looks like the address sent to was a mixer and hence it wouldn't be possible to tell who stole it. Antiviruses aren't 100% accurate and it is possible for them to miss kinds of virus infections.

Did you download the core version from the official website? That would be the single most important thing to do to prevent this kind of theft.

You could also run some other anti virus to be absolutely sure. I don't think windows 10 is the problem here, else a lot more people would have been having problems with this and microsoft would be biting some serious dust right now.

Did you use any of the password in any other places? E.g. Bitcointalk, Gmail?

You can insert a picture by going to imgur.com, upload and post the link to the image here. Newbies cannot directly post pictures.

I was considering to invest in Bitcoins but seems like it is not secure.
Is there any method to protect bitcoins from a robber.
31 Bitcoins ($ 12,090.07) What a huge amount of loss to Edward.

I've never written my passwords
From 2nd wallet:

2 transactions
the 1st one has no address

[helloeverybody]

I've seen a few key loggers that are almost invisible to most anti virus.  With any serious amount of btc I recommend cold storage.  In this case it would be too little too late obviously.

[Jeremycoin]

Do you mean that someone sent all of your BTC from your wallet? Or they stole your private key? Or Both?

https://blockchain.info/address/15ESHhWuNfqMEQPXWexGb9kK1J53brWksL

Oops, I'm sorry. I didn't see that you give a link to the transaction
So the hacker sent your Bitcoin, right?

[NorrisK]

Your system is definately compromised. Best thing might actually be to do a clean install and get a new set of private keys.

What ever you do, do not touch your keys ever again, the hacker will always have access to them.

[Familiar]

Your system is definitely compromised. Best thing might actually be to do a clean install and get a new set of private keys.

Whatever you do, do not touch your keys ever again, the hacker will always have access to them.

It indicates that he will never get his bitcoins back again?
He can't complain regarding the issue to somebody?

The chances of him getting those back are slim to none.

There is always the possibility that it was someone close to him that had physical access to his pc at some point.

Yes there is! For such a huge amount, OP should have used paper wallets or have bought a hardware wallet like a Bitcoin Trezor. Any of these two combinations is perfectly safe and should be used for anything over 7-8 coins in my opinion.

OP sorry for your loss by the way!

Your system is compromised. Either that or someone had access to your computer physically.

Use a cold wallet (paper wallet) or Trezor. Nobody can hack a piece of paper and I heard good things about trezor

Nobody can hack a piece of paper but they can hack the medium which is used to sign the transaction. Hardware wallets or an offline computer(raspberry pi) is a much better alternative. Even Ledger wallet is good enough.

Last time I've entered the password many mounth ago.
Nobody has offline access to my laptop and my desktop and nobody knows my passwords (they were different)
After manipulations the 2-and wallet is decrypted now.
The laptop very often is offline. Sometimes I update the bitcoin core.

[Amph]

it is best to avoid windows 10 right now, but i don't think this is the case, of the first hacking attempt from microsoft, so it most likely that you were infected

you visited a shady website or probably downloaded something malicious, in other words it's your fault
